Some of my application have become so rock solid that the customers choose
not to upgrade to newer versions. I can't do anything with those already
decided so, but in the future I might be forced to time-out my applications
if there is no valid subscription.
I wonder if there is a good way to verify the Setupbuilder generated
subscription key when executing the _installed program. Currently I have
saved the key and expiration date in a registry key, but we all know how
easy is is to change the date in registry. Is the VerifySubscriptionKey
function perhaps available in a dll I can use?

Thanks
